; }1c1 i .,(c1. 149-2 6) My invention relates generally to means forclipping and trimming furs; and an important object of the invention'isto provide means whereby the fur skins are exactly held While beingcarried past a setof revolving knives which clip the hair to any setlength, whereby complete and accurate trimming of the skin is achievedin one operation, wherein the hair over the entire length i and width oftheskin is uniformly clipped;- Another important object of myinvention'is' to provide a simple and practical arrangement of this'character which does not require extensive handling of the skins;v andwhich can be operated by unskilled persons. I

l5- Other important objectsv o'f'my inventionwill be apparent from areading of the following de.-'

scription taken in connectionwith the drawings, wherein for purposes ofillustration 1 have shown preferred embodiments of my invention. Y Inthe drawings:

Figure 1- has a right hand elevational view of an'embodiment oftheinvention. 1x. Figure 2 is a back view of Figure 1 taken looking fromright to left in Figure 1 with the cutter removed. 1 Figure 3 is alongitudinal vertical sectional view taken through Figure 1 the sectionbeing taken on approximately the line 3-3 of Figure 1. Figure 4 is atransverse vertical sectional-view 30,; taken through Figure 2 thesection being'taken on approximately the line 4-4 of Figure 2.

Figure 5' is a transverse verticalsectional view I taken through anotherembodimentiof my in-- vention. 35: In the drawings, and referring-firstto the embodiment of the invention shown in Figures 1 through 4, thenumeral 5 generally designates a A suitable support on which are"mounted two end plates 6 which are annular inform and have 4()"-radially'extending lugs I which act as journals for the various roller'shaftsto be described. The" annuli- 5 receive therethrough the suctionpipe 8 which at a point between the plates 6" has tangentially flaringsides -9 and I!) which define a H 4,57 suction opening therebetw'eenfacing the back of the machine.

J ournaled in the respective lugs l are'the' upper and lowerrollershafts II and I2; and thefront andback roller shafts I-3"and M, theshaft II 5.0 5 having a surrounding roller I I, the shaft [2 a rollerI2, the shaft l3 a roller l3 and'the shaft 14 a roller l4, all of whichrollers engage the inner side of va cylindrical casing l5 which isrevoluble by reason of this arrangement and has 55 over its surface .theperforations :IS a portion of which are adapted to'register with theopening definedby the suction pipe flanges 9 and ID as they come intoregistry therewith. The shaft 13 extended beyond its supporting lug landhas a pulley l'l thereon which may be driven'by a suite 5 'l5at'the"required rate of speed.

-I-Iaving their opposite ends journaled in spaced 'ablevb elt"(notshown)for revolving the cylinder members of thesupport '5 are roller shaftsl8,

I9 andjZfl-which have trained-thereover'the belt 10 2| whose upperfiight2 2 is conformed to and runs against theibottom of the revolvingcylinder l5 as 'clearlys'hown in Figures 1 and 4.

Vertical projections 23 on the respective plates -6 mounted L-shapedbrackets 24 whichare piv l5 oted as indicated by the numeral 25 to thepro--' jections and carry at their outer ends or front ends the shaft216 which mounts a heavy roller 21 over which is trained a. belt 28whose lower'flight 29 conforms to and rides upon andis driven bycon- 20tact with the. surface of the upper part ofthe revoluble drum l5.Another shaft 30 is supported at" its opposite ends-byvarms-"3l pivotedas indicated bythe 'numera1v32 to the back part of the projections 23'and carries a smaller roller 33 over 25' which the belt '28 also'istrained. In addition the arm'silihavemounted thereon the beam 34 towhich are attached and from which depend the pressure fingers35 whichengage the back part of the-cylinder l5 as clearly'shown in Figures 1 30and 4 andal'so in Figure 2. g The remainingarms of the L-shaped levers24 have mounted thereon the shaft 36 which contains the roller 31, Theshaft 36 is mounted" in a" slide bearing arrangement 38 on each'of the35 5 armsof the'lever s 24 which by reason ofwhich a screwarrangements!) is adjustable to different g positions to ride againstthe upper flight 40 of the belt28.. v, r

A contracting spring H is stretched between 40 ond tensioning spring42is stretched between'the v roller part of each arm 3| and each of the,pro- "jection's 23- as}illustrated in Figure 1 for tensioning the roller33 against the upper back part of the revolving cylinder and in additionto tension the spring fingers 35 against the back ofthe revolvingcylinder.v Mounted'on the support 5 immediately .to the rear of therevolving cylinder I5 is the cutter cylinder 43 which is mounted on arotaryshaft 44 and is shielded by a shield 45. The cutter '55 the sameagainst the upper part of the cylinder and acts to make the same engagethe cylinder evenly throughout the length and width'thereof,

the skin being engaged by the lower flight 29 of the belt, and the beltholds the: skinin engage? ment with the cylinder I5 until the cylinderwith the skin thus held thereon turns to a point where the perforationsl5 register with the opening in the suction pipe, whereupon the suctionin' the" suction pipe will strongly and evenly secure the skin to theexterior of the cylinder so that all unevenedges will be exactly held.The skin and alllparts'thereof thus held against the exterior of thecylinder by suction, is carried down under the tensioning fingers 35until exactly in a position to have theiur thereof clippedby thecooperating knives 45 and 41.

Thearrangements are such that as the edge of the skin passes the regionof the 'clipping, the same :will engage between therbelt 2|" and thelower part of the cylinder;;and pass from the region of thesuction-opening :'to the bottom .of'the cylinder, the exact positioning'of the skin being maintained by the.:portion of the skin which is overthe suction hole and that. portionof the skin preceding the same whichis held in place on the cylinder by the belt 2i; whereby the skin,throughout its operative engagement with the cylinder 15, is held inanexact, smooth,,and even contact with the drum, so: that absolutelyuniform clipping 'of thexhair thereof throughout the length'and width ofthe skin is accomplished by passing the same once through the machine.The position of the stationary knife 41 and of the revoluble knives 45may be altered to achieve the cutting of the hair of the skin at-thedesired length. In Figure15 of thedrawings another embodimentof theinvention is shown and'comprises a large 'revoluble cylinder 50 whichhas-trained thereover a perforated belt 5! which has a horizontal flight5-2 which is the upper flight and an angulated flight 53 which is thelower flight, The

upper flight 52 is passed across the horizontal top. .5 t'ofi-a suctionconduit 55 which has'in its top an opening 55 whose presence causes theexertion of'sucti'on: through the holes or perforations 5'! in the belt5i. The conduit 55 is projected from the suction pipe 53'around whichthe belt 55 moves as indicated, and brackets 59 projecting from theconduit, carry spring fingers 58 which bear against the back of the beltpassing aroundthe pipe 58 as clearly shown in Figure 5 to guide the skinpast the fur cutting stationary knife 41' and the revolving knivesn ifi,the latter being mounted on a shaft which is driven from .a suitablepower source. is provided'forprotecting. the. rotary cutter.

' Engaging the right hand portion of the bottom leading- An' overlyingshield 4-5" upper flight 52 of ,the belt back of the suction opening '56and the belt carries the same along until the opening 56 is reached,whereupon suction is transmitted from the conduit 55 through the holes51 in the belt to the skin, whereby the skin is positively evenly heldon the belt and transportedtoward and into engagement with the springjfingers '60 which hold the same in the proper position for clipping ofthe hair thereof by theknives. As indicated by the numeral (ii thesuction opening 56 extends down along the back 'of the suction pipe 58so as to retain the suction effect for. holding the skin until the samehasipasse'dthe clipping position; andhas engaged itsforward edge withthe flight 22 of the belt 2l'-, which then mechanically holds the skinuntil the skin has passed the related position.

, It is to be noted that neither the perforated cylinder l5northeperforatedbelt 51 has to-be perforated over its entire widthand lengthor held to the cylinder or belt by the spring pres sure fingers 35.Where-more than one type of work is tobe done by one machine,.shields ofimpervious material may be applied to a completely perforated cylinderor belt to close off the undesired perforations.

Although I have shown and described herein preferred embodiments .of myinvention, it is to be definitely understood that I do not desire tolimitthe application of the invention thereto, and any change or changesmay be made in the materials, and in the structure and arrangement ofthe parts, within the spirit of the invention and the scope of thesubjoined claim.

What is claimed is: a

A machine for clipping the fur or hair or skins comprising a cylinderhaving perforations therein, means for rotating the cylinder, a suctionchamber inxthe cylinder having an opening therein covered by a limitedarea of the inner circumferential part of the cylinder, means forcreating spring fingers carried by the second pair: of arms and engagingthe cylinder at a pointadia cent the point where the clipping meansengage the fur or hair of the skins.
